I too having "Network Conection Error" when trying to use Concur app. Changed PIN, reinstalled app but still not luck.
Working fine using laptop.
Can you help or suggest something ?
I'm having this same issue, both iPhone and iPad give the "We don't recognize the information entered. Please re-enter your username and password." error, telling me to re-enter or contact my company help desk. Logging in on PC works fine. Please advise!
